IRTlib Documentation
Software for the administration of computer-based assessments
1 Einführung / Introduction
IRTlib is a software for the delivery of computer-based tests. It consists of two components:
- IRTLib Editor: A software for test authors, which is used to configure studies.
- IRTlib Player: A data collection software program used by test-takers to complete tasks configured for a study.
Instructions for installing and setting up both programs for first use can be found at Download.
Before using the IRTlib software to configure and create deliveries, the assessment content can be created in the form of individual tasks using the CBA ItemBuilder.
The CBA ItemBuilder can be downloaded here: www.itembuilder.de/software
The interactive documentation of the CBA ItemBuilder is available here: cba.itembuilder.de
To use the IRTlib software, a context-sensitive program help is stored directly in the application. The documentation with the embedded help is available online on this page and is also available as PDF.
The development of the CBA ItemBuilder and the IRTlib software is coordinated by the Center for Technology-Based Assessment (TBA) at the DIPF | Leibniz Institute for Research and Information in Education.
